PdCurses box problem

[Lotherad]

Hello. I just installed PdCurses and I want to compile my code. In begining I wrote this:

#define __cplusplus
#undef box
#undef clear
#undef erase
#undef move
#undef refresh
#undef stdscr 

And everything seems to be fine but I'm getting error:

D:\Program Files\CodeBlocks\mingw32\i686-w64-mingw32\include\pdcurses.lib(border.obj):z:\PDCurses\pdcurs|| multiple definition of `box'|

In line

void my_function()
{

If someone can help it will be awesome.

EDIT.

Okay, I solved it. Problem was in variable name. It can't be "box". :P
